Specification of Letters Patent.

Yatented Sept. 18, 1906.

Application filed November 13,1905- Sarial No. 287.002.

To all whmn it may concern:

Be it known that I, WALTER HENERY FREE- MANTLE, a subject of the King ofGreat Britain, residing at Smiths Falls, county of Lanark, Province ofOntario, Canada, have invented certain new and useful Improvements inNut-Locking Devices; and I do hereby declare that the following is afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to nut-locks.

The object of my invention is to provide means for locking the nuts onaXle-boX bolts and similar bolts on railway-cars; and my inventionconsists of the construction, combination, and arrangement of parts, asherein illustrated, described, and claimed.

In the accompanying drawings, forming part of this application, I haveillustrated one form of embodiment of my invention, wherein similarreference characters designate corresponding parts, and in which Figure1 is a side elevation of one end of an ordinary railway-car truck,showing the application of my invention. Fig. 2 is a plan view of thedevice of my invention, and Fig. 3 is a longitudinal vertical sectionthrough such device.

Referring to the drawings, A designates a truck, B the axle-box carriedthereby, C

the bolts securing the axle-box, D the nuts on the bolts, and E thelower truck-strap, all of which are of ordinary and usual construction.

4 designates the side walls, and 5 the end wall, of a locking-clip. Theside walls 4 are connected intermediate of their ends by the transversewebs 6, so that the sockets 6 are formed by the side walls 4, the endwall 5, and the webs 6. These sockets may be of suitable dimensions toclosely fit the ordinary sizes and forms of nuts used on axle-box bolts.The side walls 4 are provided with a plurality of openings 7, throughwhich may be disposed the split pins 8.

In the operation of the device the side walls 4 are disposed on oppositesides of the lower truck-strap E and the pins 8 inserted through theopening 7, so that they bear on the upper and lower faces of thetruck-strap. By having the'plurality of openings 7 the device may beadjusted to suit different forms of truck construction.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. A nut-lock comprising a casing formed with side walls and an end walland also formed with integral webs connecting the side walls and formingsockets therewith, and the side walls being provided with openingsadapted to receive securing members.

2. A nut-lock comprising a casing formed with side walls and having anend wall, and formed with sockets, one wall of one of the sockets beingformed by said end wall, and said casing being provided with rows ofopenings adapted to receive securing members.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
